(?-s-cis-1,3-Butadiene)tetra-carbonyl-chromium(0).

ABSTRACT: In the title complex, [Cr(C(4)H(6))(CO)(4)], the Cr(0) atom shows a distorted octa-hedral environment from four C atoms of the carbonyl ligands and the two ?-bonds of the s-cis-1,3-butadiene ligand. The complex has an approximate non-crystallographic mirror symmetry m passing through the chromium atom, two carbonyl ligands and the mid-point of the central C-C bond of the s-cis-1,3-butadiene ligand. The C-C bond lengths in the s-cis-1,3-butadiene ligand alternate, the terminal distances being shorter than the central distance.

In the title complex, [Cr(C(4)H(6))(CO)(4)], the Cr(0) atom shows a distorted octa-hedral environment from four C atoms of the carbonyl ligands and the two π-bonds of the s-cis-1,3-butadiene ligand. The complex has an approximate non-crystallographic mirror symmetry m passing through the chromium atom, two carbonyl ligands and the mid-point of the central C-C bond of the s-cis-1,3-butadiene ligand.

Redetermination of (?-s-cis-1,3-butadiene)tricarbonyl-iron(0).

Project description:The crystal structure of the title compound, [Fe(C(4)H(6))(CO)(3)], was previously reported by Mills & Robinson [Acta Cryst. (1963) ?, 16, 758-761]. The compound crystallizes in the centrosymmetric space goup Pnma with the complex located on a mirror plane. The redetermination of this structure at 100?K yielded almost equilibrated C-C bond lengths within the butadiene ligand according to a metal-to-ligand bonding-back-bonding mechanism. The C-C bond lengths presented herein are significantly shorter than those reported earlier. The H-atom positions that have not been reported so far were located by difference Fourier maps. The positional parameters of all H atoms and individual U(iso) values were refined freely.

trans-Tetra-carbonyl-bis-[tris-(3-fluoro-phen-yl)phosphane]chromium(0).

Project description:In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes, which are trans to each other. The three benzene rings in one phosphane ligand make dihedral angles of 53.50?(9), 75.51?(10) and 80.63?(10)° with each other, while in the other ligand these angles are 51.92?(10), 78.56?(11) and 86.80?(10)°. C-H?O and C-H?F inter-actions link the mol-ecules into a three-dimensional network. Each of the F atoms is disordered over two positions with refined occupancies of 0.944?(3):0.056?(3), 0.702?(4):0.298?(4), 0.829?(4):0.171?(4), 0.567?(4):0.433?(4), 0.545?(4):0.455?(4) and 0.920?(4):0.080?(4).

[N,N'-Bis(2,4,6-trimethyl-phen-yl)ethane-1,2-diimine-κ(2)N,N']tetra-carbonyl-chromium(0).

Project description:The octa-hedral coordination of the Cr(0) atom in the title compound, [Cr(C(20)H(24)N(2))(CO)(4)], displays some distortion. This is manifested by an exocyclic torsion angle C(mesitylene)-N-Cr-C(carbon-yl) that deviates by more than 20° from planarity. Another structural feature is the significant distortion from linearity of the Cr-C-O angles of the two carbonyl groups that inter-act with both ortho-methyl groups of the two mesitylene rings. The remaining two carbonyl groups overlap with the centres of the mesitylene rings themselves and are linear within <3°.

Project description:In the title hydrate, [Fe(2)Sn(C(5)H(5))(2)(OH)(2)(CO)(4)]·H(2)O, the central Sn atom is tetra-hedrally coordinated by two {Cp(CO)(2)Fe} fragments and two hydroxide groups.

trans-Tetra-carbonyl-bis-(tri-phenyl-phosphane-κP)molybdenum(0).

Project description:The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits significantly different Mo-P-C-C torsion angles ranging from 2.6 (2) to 179.4 (1)°, most likely due to steric inter-actions based upon their positions relative to the carbonyl ligands.
